System.IO.IOException: Invalid handle to path "/home/marcos/.local/share/tomboy/dad8b4d4-752c-4309-8b5a-ed69aa13383f.note"
That implies that something is wrong with that note file. Can you open it up in gedit or something and tell if it's corrupt?
Delete the file or move it outside of the note directory, and see if Tomboy will start after that.
